Storage class for Economy time constants.
static constexpr int DAYS_IN_ECONOMY_MONTH
Days in an economy month, when in wallclock timekeeping mode.
static constexpr int DAYS_IN_ECONOMY_YEAR
Days in an economy year, when in wallclock timekeeping mode.
Template class for time constants shared by both Calendar and Economy time.

static Date date
Current date in days (day counter).
static Year year
Current year, starting at 0.
static Month month
Current month (0..11).
static bool UsingWallclockUnits(bool newgame=false)

static DateFract date_fract
Fractional part of the day.
static YearMonthDay ConvertDateToYMD(Date date)
Converts a Date to a Year, Month & Day.
static void SetDate(Date date, DateFract fract)
Set the date.
static Date ConvertYMDToDate(Year year, Month month, Day day)
Converts a tuple of Year, Month and Day to a Date.
Template class for all TimerGame based timers.
uint16_t DateFract
The fraction of a date we're in, i.e.
uint8_t Day
Type for the day of the month, note: 1 based, first day of a month is 1.
uint8_t Month
Type for the month, note: 0 based, i.e.
